SPCFICATION forming part of Letters Patent No. 433,503, dated August 5,1890.

Application filed Jannary29, 1890. i Serial No. 338,502. (No model.)

.To all whom it may conccrn:

Beit known that I, J AY F. XVILSEY, a citizen of the United States,residing at Jerry City, in the county of WVood land State of Ohio, haveinvented certain new and nseful Improvements in Churns; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,.which form part of this specification.

My invention relates to churns of that character in which a series ofrevoluble dashers are caused to agitate the material to be churned.

The object of my invention is to provide a series of paddles or dashersset obliquely to radial planes passing through the shaft, with theinclination of each dasher directed from the outer end of the churntoward the center, whereby to not only agitate the creamcircumferentially of the axis of the dashers, but longitudinally of thechurn.

A further object is to introduce a current of atmospheric air into thechurn in such relation to the axis of the dashers that they (thedashers) by their obliquty to the axis and point of ingress of the airwill draw the same into the churn and force the air into the cream.

A further object is to cause the airto enter at the desired points ofingress and escape by a separate and distinct point of egress.

A further object is to journal the shaft upon which the dashers aresecured in a manner to allow of easy removal of the same.

A further object is to so construct the airingress ports that they maybe provided with a removable foraminous covering, thereby preventing theingress of dust or dirt particles incident to the draft of air throughthe ports caused by the Vacuum created by the obliquely-moving dashers.

The invention consists in the parts and combination of parts hereinafterdescribed, and pointed out in the claim In the drawings, Figure 1 is aside elevaM tion of a churn, showing the gearing for actuating thedashers in edge view. FigB 2 is a longitudinal vertical sectional viewthrough secured the metal U-shaped body portion B,

preferably by forming a correspondinglyshaped groove O in the end piecesand letting the ends of the body B therein, and drawng the end sectionsclosely against the ends of the body by means of rods D, extendinglongitudinally of the churn, the edges of the sides being bent aroundthe upper rods, as shown in Fig. 8. The receptacle is mountecl upon legsF, secured to the end pieces and closed by a removable cover G, formedwith an airescape pipe H.

In each end piece A of the churn-body there is formed a verticalair-duot I, leading from the top down to near the middle portion of theend piece. Communicating with this vertical air-duot near the top is anouter lateral Opening J for admitting air from the outside, whichope'ning is guarded against the ingress of dust, &c., by a removableforaminous covering K, held in place by being se cured to a frame whichslides in ways K' attached to the end piece A, and at the bottom of theair-duot I there is an inner lateral Opening J' on a line with the uppersurface of the dasher-shaft.

L designates the dasher-shaft, the body of which is formed of wood, uponeach end of which is secured metal thi mbles, one of which L' is formedwith a rectangular perforation in the end to receive the Square end of ajournal M, having a bearing in end piece A, upon which there is secureda pinion M' which meshes with a gear-wheel N, journaled in the upperportion of the churn, and provided with a cran-k N'. The opposite endhas a thimble L secured theren, which has a semicircular'recess intowhich is centered a bearing O, screw-threaded to run into a nut O' setinto head A' the end of the bearing O being provided with a thumb-holdby which to set the same to any desired adjustment-flas a pivotalbearing-fl-and being held to the ad- IOG jnstment by means' of a nut P,run upon the i same, and which bears upon the nut O' frictionally toprevent the bearing from unscrewing.

P' designates pins passed through shaft L at diametrically-oppositepoints, upon which are Secured the dashers Q, one upon each end, thedashers being inclined oppositely and at oblique angles to a radialplane passing through the shaft, Whereby in the revolution of the shaftthe outer ends of the dashers-- e. those ends`nearest the ends of thechurn-have an inclination toward the center of the churn, thus causingthe cream to be moved circnmferentially of the axial plane of the shaft,and-also longitndinally of -the,same, .thereby by: pressure divestingthe butterglobu1es of the membrane that .iincases them as the cream isnrged to :the center by theobliquity of .the dashers-an-effeot farSuperior tothat caused by directimpact of thedashers.

An important: result attained by locating the. air-inlets .v J on :aline-With the dashershaft and having one of .these inlets at beachsideis that,-owing to the vacunm in .the vicin ity of these inletsvcaused by the revolution of thevdashers; a constant-cnrrent of air isdrawn into thev churn froin each side, meeting in the middle. along theline-of the shaft','fron1 which position,-.as the fiuid is urged towardthe center, it -isthoroughly.distributed an d incorporated into thecream-,,thereby, on awelLknoWn principle, causing the butter-globules toreadily separate from the cream, and also serving to carryoif` theimpurities of the latter.

In order to provide means for cleansing the air-ducts, the openingsextend through the Upper. ends of the end sections, as shown, WherebyWhen :the cover G and the forami-` nous coverings K are removed Watermay be poured into the vertical passages Lwhich, findi ing its. egressinto the churn, removesany butyric particles that may have been forcedtherein.

In order to remove the dasher-shaft, the nut P is run back, therebyallowing the journalbear-ing O to beunscrewed from contact With thebearing' in thimble L' when by inclining the shaft it can be withdrawnfrom the churn.

It will be understood from the for-egoing de4 scription that by theagitation of the cream longitndinally in opposite directions, and alsospirally, due to the obliquity of the dashers, thewhole mass of cream isagitated evenly, thereby convertin g the maximum amount into butter of afiner -texture thaniwhen theope-r- -ation is eifected by direct impact,and that by reasonof the obliquity-of the dashers and the relativepointof ingress of air'thereis-in- So sureda const-ant currentofv air in=incorporation `With the cream.

-WVhat I claim is-- Ina ehurn having a ho'rizontal-da'sher-.shaftjournaled therein, endse'ction of' thechurnvbody having vertical:air-ductsr; leading from the top-downward toward theshaft, lateralair-pass'ages. leading' from the outer side of the churn to said'dnctsand lateral. air-passages leading from the bottom-of- `the ducts yo tothe inner side of. the:chnrn,.and.a churncover closing .the upper endsof the'airkducts and having an air-vent, for the purposesset forth.
